IMPROVEMENT IN DRAFT-HOOKS FOR CULTIVATORS.

Specification forming part of Letters Patent No. 139,752, dated June 10, `1873 application filed January 4, 1873. l

To all whom it may concern:

Be it known that I, AUGUSTUS ADAMS, of Sandwich, in the county of DeKalb, and State of Illinois, have invented a new and Improved Draft-Hook for Uultivators; and I do hereby declare the following to be a full and exact description of the same, reference being had to the accompanying drawings forming part of this specification, in which Figure l is a side elevation of a cnltivator with my improvement attached. Ijig. 2 is a perspective view of a double-tree, showing theapplicatiou of the draft-hooks and plate. y

Similar letters of reference in the accompanying drawings denote the same parts.

My invention has for its object to 'provide means for adjusting the line of draft in cultivators for the purpose of balancing the varying weight ot' drivers in riding-cultivators, and to lift the weight from the necks of the team in a walkin g-culti vator, To this end the invention consists in a metal arm adapted for attachment to the end of the double-tree, and cast with draft-hooks, one or more above and one or more below the evener.

In the accompanying drawings, A is the metal arm formed upon or attached to an eye, B, which is securely fitted over the end ot' the evener so that the arm shall depend downward therefrom. The arms may be attached to the evener by any other suitable means, though I prefer the eye B, as being economical and secure. In this example of my invention the points of attachment for the whifdetrees are composed of draft-hooks D E F, formed upon the metal arm at different heights, two below the evener and one above it. The lower hook D may also be curved to the front instead of rear, as shown, this difference being merely one of choice.

When a cultivator is in use, with the driver riding, his weight tends to tip up the tongue l and lift the neck-yoke against the throats ot' the horses. It is difficult, therefore, to hold the tongue down so that the machine shall run steadily. To prevent this difficulty the whiftletrees are hitched tothe upper portion of each arm; the draft of the team then tends to bear down the end of the tongue and counu so much asf frequently to chat'e the necks of the horses and render them very sore. To obviate this the whiffietrees are hitched to t-he lower portions of the arms; the draft of the team then tends to raise the tongue and re" lieve the pressure upon the necks of the horses. l

The intermediate points of attachment ,are

employed to receive the whiftletrees for counv terbalancing the weight of light and heavy drivers, or different degrees of downward pressure at the end of thetongue. By my invention the whiiietrees are adapted for ad` ,p

justment to counterbalanee the weight of riding drivers, and prevent the necks of the horses from being injured when the driver is Walkin g. v

G is a plate secured to the evener at the middle so as to come het eenitand the tongue and project beyond the evener either forward or backward, or both. By this provision a wide bearing is afforded on the tongue for the purpose of preventing the evener from wringing or twisting when the draft is ap plied to the arms either above or belowA the I am aware that a single drafthook, pendent from the end of a double-tree, has heretofore been used, but such construction Ido not claim.

Having thus described my invention, what I claim as new is- A draft-hook for cultivators adapted for attachment directly to the end of the evcner or double-tree, and cast with a number of drafthooks, one orA more above and one or more Y below the evener, substantially as described,

for the purposes specified.
